Abstract

The same track on an optical disk (1) is read at least twice by an optical pickup (3) at a speed rich is at least twice a standard speed to store the read information into a memory (7) at a time of the first reading corresponding to a memory periodic interval (Mn). When an erroneous track jump has occurred, the optical pickup (3) is returned to the track on which the erroneous track jump has occurred and the read information from the track is stored into the memory (7) during and empty interval (En).
